MISSING PIECE:Carmelo Anthony will be on hand but Amar’e Stoudemire will not when the Knicks open their season tonight.

The biggest question of the Knicks’ season has been put on hold for the next two months.

The anticipated glitz-and-glam start for the Knicks, which includes tonight’s home debut against the defending-champion Heat, has lost some luster because of a myriad of injuries that have hit the team. The most damaging is the loss of Amar’e Stoudemire for 6-to-8 weeks, after surgery on his left knee.

That layoff will stunt any further development of the much-questioned chemistry between the power forward and fellow star Carmelo Anthony.

“We still don’t know. That’s one of the X-factors if those two guys can still find harmony together,” MSG Network analyst and former Knicks great Walt “Clyde” Frazier said. “So, that’s why everyone was excited, even [coach Mike] Woodson with Melo [and] Amar’e having a full training camp, which they didn’t have last season to work that out. We really don’t know now.”

Another thing the Knicks really don’t know is how serious Anthony was about his offseason claim to have a greater willingness to share the ball if it was for the betterment of the team and led to more wins.

Dating back to his days with the Nuggets, Anthony had been criticized for his perceived selfishness.

“I’ve told Melo, ‘You should be a 20-10-5 guy.’ He just laughed, so I don’t know,” Frazier said. “The definition of being a superstar is the guy that makes the guys around him better. So, if he’s going to do that, he needs to have more versatility, which I think he realizes.

“He’s saying all the right things. If he can rebound a little bit more, do a little more dishing. His defense definitely improved under Woodson. He responded by working a little more diligently on defense.”

Frazier said he saw the Knicks’ offseason additions of veterans Rasheed Wallace, Marcus Camby, Jason Kidd, Raymond Felton and Pablo Prigioni as a sign the team thought it could be a championship contender immediately. Felton will start at point guard and be charged with replacing the uber-popular Jeremy Lin, whom the Knicks let leave for the Rockets.

“[Felton] seems to be the same guy getting to the basket, relentless in his pursuit, moving the ball up and down the floor,” Frazier said. “He’s a guy that has a lot to prove. He’s wasted two years. Once he was traded from the Knicks, he languished in Denver and was worse in Portland. He knows the focus is on him, and he’s really happy to be back in New York. He’s playing with a chip on his shoulder.”

But Felton is one of the few Knicks completely healthy after a painful preseason, which could make it difficult to judge how good they really are in the early season.

“I don’t think it is a good barometer of where the Knicks are because they are not healthy,” Frazier said. “You can’t say what’s going to happen a month or two from now when everyone is healthy and playing ball.’’
